" This article contains a plethora of information on EVDO and mobile broadband
Getting online and being able to connect with friends, family, news, and the office is more important now than ever, but what happens
"Mobile Broadband" is a generic term that describes this type of internet connectivity, but there are a few related terms that will be helpful to understand.
598U, CTR350, and Booster Antenna
a popular EVDO setup: a Sprint 598U aircard in a Cradlepoint CTR350 router to share the connection, with a Booster Antenna to improve signal
Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-Do, EV, EVDO, etc.) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EV-DO is an evolution of the CDMA2000 (IS-2000) standard, but EV-DO will support high data rates yet can be deployed alongside a wireless carrier's voice services. So EV-DO now (2013) stands for "Evolution-Data Optimized" It uses advanced multiplexing techniques including code division multiple access (CDMA) as well as time division multiplexing (TDM) to maximize throughput. It is a standardized part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world - particularly those previously employing CDMA networks such as 3G. It is also used on the Globalstar satallite phone network.
An EV-DO channel has a bandwidth of 1.25 MHz, the same bandwidth size that IS-95A (IS-95) and IS-2000 (1xRTT) use. The channel structure, on the other hand, is very different. Additionally, the back-end network is entirely packet-based, and thus is not constrained by the restrictions typically present on a circuit switched network. ..." ... continued ... (see below).
